They are supposed to be used first thing in the morning but what about after night shift?
I usually go to bed at 8.30am, get up for a wee around 10.30am then if I'm on 1 night I get up at 1pm. If I'm on another night I get up at 5pm if I can sleep that long.
So generally I don't have long period if sleep so when would be best to test?
